Method of transforming impedance and coplanar multi-layer impedance transformer

摘要

Method of transforming impedance in a structure, said structure comprising a coplanar line between a lower ground plate and an upper active plate, the method comprising: providing N-1 substantially parallel conducting layers, being N>2, inside the ground plate and the upper active plate of the structure, thereby having N coplanar lines, injecting a current in a single first input layer, being said single first input layer the layer above the ground plate, and using said N coplanar lines as output, whereby at the output the voltage is divided by N, and the current is multiplied by N, being the impedance multiplied by N². The invention also relates to a coplanar multi-layer impedance transformer.
